Download Boil Water Advisory Frequently Asked Questions

Non-potable water sources include rainwater, reclaimed/recycled water and gray water. While non-potable water is
not appropriate for human consumption, it can be used in a myriad of other applications, such as doing laundry, toilet
and urinal flushing and cooling tower make up water. Nonpotable reuse projects treat wastewater for specific
purposes other than drinking, such as industrial uses, agriculture, or landscape irrigation. Nonpotable reuse could
also include the use of reclaimed water to create recreational lakes or to build or replenish wetlands that support
wildlife.
Boil Water Advisory Frequently Asked Questions
1. Why do I have to boil my water?
A "Boil Water Advisory" is a notification issued by your public utility as a preventative measure. Boil
water advisories are distributed if there is actual or the strong possibility of bacterial contamination in
the drinking water system that could make you sick.
2. Should I use bottled water?
Water from an alternative water source is the best option during a boil water advisory. When bottled
water is available, it is a good alternative to boiling water.
3. What is the proper way to disinfect my water so it is safe to drink or prepare other
drinks like baby bottles, kool-aid, sun tea, ice tea, frozen juices etc.?
The best method of treatment is boiling. Boiling water kills harmful bacteria and parasites (freezing will
not disinfect water). Bring water to a full rolling boil for at least 1 minute to kill most infectious
organisms (germs). For areas without power, disinfect tap water by adding 8 drops, about 1/8 teaspoon,
of plain unscented household bleach to a gallon of water. Thoroughly mix the solution and allow the
water to stand for 30 minutes. If the water is cloudy, repeat the process. Use a container with a cap or
cover for disinfecting and storing water to be used for drinking. This will prevent re-contamination.
4. Can I use my coffee maker, ice machine, water or soda dispenser?
Do not use if they are directly connected to your water supply. Use bottled water or water that has been
boiled or disinfected for making coffee and ice. Also, filters don’t work for removing bacteria. Once you
have been notified that the boil water advisory has been lifted, these devices should be cleaned,
disinfected and flushed according to the operator's manual for the device.
5. Can I use tap water to brush my teeth?
No. Do not use tap water to brush your teeth. Use bottled water or water that has been boiled or
disinfected as you would for drinking.
6. How should I wash my hands during a boil water advisory?
Vigorous handwashing with soap and your tap water is safe for basic personal hygiene. However, if you
are washing your hands to prepare food, you should use boiled (then cooled) water, disinfected or
bottled water with handwashing soap.
7. Is potentially contaminated water safe for washing dishes or clothes?
Yes, if you thoroughly rinse handwashed dishes for a minute in a bleach solution (1 tablespoon bleach
per gallon of water). Allow dishes to completely air dry. Most household dishwashers don’t reach the
proper temperature to sanitize dishes. It is safe to wash clothes in tap water.
8. Is potentially contaminated water safe for bathing and shaving?
The water may be used for showering, baths, shaving and washing, if absolutely necessary, but don’t
swallow water or allow it to get in your eyes, nose or mouth. Children and disabled individuals should
have their bath supervised to make sure water is not ingested. Minimize bathing time. Though the risk
of illness is minimal, individuals who have recent surgical wounds, have compromised immune systems,
or have a chronic illness may want to consider using bottled or boiled water for cleansing until the
advisory is lifted.
